Fig. 13 is a vertical cross-section, taken in the plane of the line 12-42 of Fig. 10, showing the printing plate in curved form.

Myinvention is especially applicable for curving printing plates for mounting the same on so-called plate cylinders in rotary printing presses. Such plate cylinders are of dilferent diameters on different presses, and I therefore further provide means whereby the printing plates may be curved to curvatures of different diameters for coaction with plate cylinders of dilfe'rent diameters.

In accomplishing the curving of the printing plate I employ a rollable mold and a between which and the rollable mold the printing plate is received. ll further employ means for maintaining the flexible band under tension while it and the printing plate are being wrapped about the rollable mold, thereby bending the printing plate to a curvature corresponding to the curvature of the periphery of the rollable mold, determined by the diameter of said mold. In order to render the printing late more readily bendable, I prefer to su ject the same to heat prior to the bending thereof. The curved printing plate produced by employment of my invention has the printing lines of its printing surface maintained in the spaced relations Which they occupied prior to the. curving of the printing plate.

In the present exemplification there is a forming mold 21 having an outer periphery 22 in the form of a substantial part of a cylinder. which ooacts with the printing plate is preferably integral.

A frame 23 is provided with racks 24 at the front and rear thereof. and with bearers 25 proximate to the racks. The forming mold is provided with gears 26 at the respective ends thereof, adjacent to which there are annular bearers 27. The gears mesh with the racks, and the annular'bearers coact with the bearers 0n the frame, so as to The forming portion of the mold lindrical surface of the forming mold and a printing plate support 28, above which the printing plate, represented at 31, isarranged to be supported during the curving oper ation.

' slab b The printing plate is exemplified as a printing plate in unfinished state, and as having the usual bearers 32, 33, separated from the printing surface 34 by the usual grooves 35, 36, and if desired, the rear face of the backing of the printing plate may be provided with recurrent depressions 37, forming ribs38, which may extend in any desired direction across the back of the printing plate. I j

The printing plate may be formed in any ordinary or usual manner and be for instance an electroplate comprising a printing shell 39 of electro-deposited metal, having a higher fusing'point, and a backing 40 of metal or material having .a lower fusing point, although printing plates otherwise formed may be curved by my improved apparatus.

The support may be in the form of a heat er, comprising a slab of desirable metal for readily transferring heat, and heated in suitable manner, as by means of electric heating elements 41, which vmay be inthe form of usual electric resistance strips,-su1tably insulated, and held to the supporting cross cleats 42, these heating, elements eing provided with electric terminals 43, 44, connecting with bus-bars 45, 46, with I which the electric connections from a suitable source of electric supply may connect, suitable heat controlling and regulating and switching devices being located in theelectric circuit for proper regulation and control of the heat for the heating slab.

The heating slab may be supported on suitable flanges 48 extending from the frame, and separated from said flangesby suitable insulatingblocks 49, to avoid transference of said heat from the slab to the frame. I r

The printing plate is arranged'to be placed on a bending element shown as a flexible band 51, hereinafter more particularly de-' scribed, supported by the support,-with the printing surface 34 of the printing plate presente toward said support. If desired, a suitabe cushioning sheet 52, as oifoil-v saturated book-paper of ordinary thickness,

' is interposed between the, flexible band and thilewprinting plate. 1 eans may also be provided for pressing the printing plate toward the slab during the heating of the plate, instanced' as accomplished by means of presser feet 54 located in socket-pieces 55 depending from guides 56, slidable along pressure bars 57, and held in adjusted positions by set-screws 58..

Pressure shoes 59 of greater area may also be laterally by wise of a rod 68, fixed to arms 69 fixed tothe rock-shaft. The. pressure bars are ad 'justable laterally'for placing the presser feet and presser shoes in desired positions with relation to the printing plate, the bearings being 'fixed to the rock-shaft 66 in adusted positions by means of set-bolts 7 0.-

The rock-shaft 66 is journaled inbearings 71 on brackets 72 extending from the frame. Counterweights 73 are fixed to the rear overhanging ends of the pressure bars for norally moving the pressure bars into out ofthe-way position. 7 r

The pressure'bars are held in down posi tion for maintaining pressure of the pressure feet and. pressure shoes upon the printing pl'a te during heating of the latter. as by means of latches '75 arranged to engage a latching bar 76 on the frame. These latches are pivoted on pins 77 in forks 78 at the forward ends of the pressure bars, being normallyf'jprged into engaging relation with the latching bar by means of springs 79-. Stops 8O limit the swinging movements of the latches toward the latching bar. fora so ready passage .of the latching end of the latches'along the side of the frame into latching'engagement with the latching bar. The latches are readily released by the operator pulling on handles 81 thereon.

The printing plate is positioned parallel With the axis of the mold, s0 thatthe curvature of the latter shallbe parallel with the printingplate. This positioning is ,aided by means of ages 85, adjustable on' arms 86, and held in adjusted positions by set screws 87, the arms 86 being adjustable llavingtheir bearings 88 adjustable lengthwise on a rod 89, and fixed in adjusted positions by set-screws 90. The rod 89 is fixed to arms 91 havin bearings 92 about the rock-shaft 66. One 0? the pressure bars is provided with a latch 93, pivoted theretoon a pivot 94, in, such relation to the rod 89, that when the pressure bars are dearticulation with the latch at 96, and supported in eyes 97 on one of the pressure bars. A collar 98 and a spring 99 position the pullrod. When now the pressure bars are allowed to rise, the gages remain in position for gaging the placing of the printing plates.

The retraction of the pressure bars may be cushioned by a spring 101 extending between an arm 102 secured to the rock-shaft 66 and the frame, the spring being located about a rod 103 articulated with said arm and between a collar 104 on said rod and a bearing 105 on the frame through which said rod slides.

The rock shaft 66 is provided with an arm 106. A link 107 is articulated with the arm at 108 and with a bell-crank lever 109 at 110. The bell-crank lever is pivoted on a stud-shaft 111 extending from the frame. A treadle lever 112 in the form of a bellcrank is pivoted to the frame on a stud-shaft 113. A link 114 is articulated at 115 with the bell-crank lever 109 and at 116 with the treadle lever. v

When the treadle lever is depressed, the

- arm 106 is caused to descend, thereby caus- All - condition of the backing latching bar ing the pressurebars to descend for pressing relation of the pressers thereon with the printing plate, the latches 75 engaging the 76.- When the printing plate has been properly heated, the latches are released, whereby the co-unterweights cause the pressure bars to rise, carrying with them the gages 85 and the parts,

same are mounted.

The printing plate is preferably placed in a position above the heating slabwith its side edges 117 substantially equi-distant from the side edges 118 of the heating slab, in order that the most uniformly heating part of the heating slab may act upon the printing plate for heating the latter uniformly throughout its area.

If desired, the heating may be of suc temperature and duration as to cause a heat material which is fusion at the time of curvfurther, if desired, be accordnear its point of ing, and may ing to the teachings of the. Claybourn Patent No.'1,318,967, dated October 14, 1919, for method of curving printing plates and printing plates curved thereby.

The presser feet and presser shoes and the pressure bars and latching means therefor, and .thegaging means, may be substantially as shown and described in Letters lPatent No. 1,372,064, to L. W." Claybourn, dated March 22, 1921, for apparatusfor curving printing plates.

The rollable mold .21 is trunnions 121. journal-led in bearings 122, re-

ceived in guideways 123 of end-frames 124.

The bearings are shown provided with slots 125, in which the side walls of the guideways 123 arereceived for positioning said bearings endwise. I

The end frames are provided with. in-

wardly extending studs 127, on which rollers 128 are held endwise. the rollers beingrota= rolling lengthtable about said studs and on which the I provided -with wise of guideways 129 in the front and rear walls of the main frame. The lower and upper walls of the guideways support the end frames and prevent rise of the same.

A cross-shaft 131 connects the end frames, being journaled in bearings 132, 133, therein, and having pinions 134 fixed thereon, which pinions mesh with the racks 24. collar 135 is fixed to one end of the crossshaft, and a hand-wheel 136 is fixed to the other end thereof. The end frames are positioned lengthwise of the cross-shaft between the pinions 134, fixed to said shaft, at the inner faces of said end frames, and the collar 135 and hand-wheel 136 at the outer faces of said end frames, forming a carriage for controlling the movement of the rollable mold.

When the cross-shaft is rotated, the pinions rotate with relation to the racks. causing the end frames to move parallel with each other lengthwise of the racks, this movement of the end frames and carriage causing the rollable mold to roll in parallel lines by reason of the meshing of its gears at its respective ends with said racks, in order that parallel bending of the printing plate is efi'ected.

One end of the flexible band has connection with the rollable mold, and the other end of the same is held by a relatively stationary part, for causing awrapping of said flexible band and the printing plate thereon about the rollable mold, when the latter is rolled over the printing plate.

The connection between the end of the flexible band and the rollable mold is preferably releasable. This may be accomplished by a hook-bar 141, extending lengthwise of the mold, and provided with a longitudinal groove 142, releasably received over a lip 143 of said mold. The flexible band may be secured to said hook-bar by rivets.

The outer wall 144 of the hook of said bar is preferably of a thickness to correspond to the thickness of the printing plate, in order to provide a printing plate space 145 between the flexible band and the periphery of the mold.

The other end of the flexible band is provided with anchoring means. Thus the flexible band may be provided with a crossstrip 146, to cured, as by riveting the same thereto.

A positioning bar 150 extends crosswise of the frame, its ends being formed as tongues 151 received in and guided by the walls of guideways. 152, in guide-bars 153, on brackets 154 of the frame. Adjusting screws 155 are journaled in the ends of said guide-bars, and threaded into threaded holes in said positioning bar, the threaded rods being provided with turning means, as handles 156, for turning the same, and thereby adjusting the position of said positioning which the flexible band is se- V I ,bar, and consequently the position of the flexible band, with relation tothe-rollable mold and the heating slabs Springs 157 are preferably interposed be tween the flexible band and the positioning .bar for providing continuous tension upon the flexible band. The respective ends of alsobe provided. Each of the Thus I have shown a rollable mold of. larger diameter in Fig. 8, and a rollable mold of smaller diameter in Fig. .9. Rollable molds of intermediate diameters may molds is rovided with a coacting'lip 143, with w ich the hook-bar of the flexible band is arranged to releasably connect.

\ Each of the rollable molds is so placed in the machine that the middle portion of its forming periphery,- instanced at 161,

shall .coact with the middle portion 162 of the printing plate which is centrally placed upon the heatin slab. I have found that best results are 0 tained by this relation, for the reason that the printing plate is thus subjected to most uniform heat throughout its area, and the most, desirable portion of the periphery of the rollable mold coacts with the printing plate. I I

This most desirable ortion is backed b l a cooling agency, whici may be a body 0.

'- water in'a cooling chamber 165 in the .mold.

The water may be introduced into said cham ber by means of .hoses 166, 167, connecting with said chamber by means of nipples 168, 169, and leading respectively from a-"suitable source of supply and to a waste pipe, the hoses being connected, with suitable valves, not shown, for regulatinfg the supply of cooling fluid and the heat 0 agency in the chamber.

The I adjusting means for the anchored end of the flexible band are provided for shifting the flexible band laterally, in order to compensate for different diameters of the cooling rollable molds, and the different positions ,of

the connection of the flexible band therewith, for effecting proper corelation between said rollable mold and the printing plate placed as stated on the heating slab. It will be noted by a comparison of Figs. 8 and 9, that 1 the greater the diameter of the rollable mold, the greater is the distance of the connection the diameters of the curvatures to of the flexible band therewith from the x'ne dian portion of the heatin slab when said rollable mold is in retracted position.

Means are provided for limiting retraction of the carriage controlling the molds,

of different diameters. In order to correctly position the carriage in the retracted position, I provide an adjustable stop, shown as a lug171 on the slide frame, and a coacting stop 172 in the form of a pin insertable in holes 173 in the frame, the various holes corresponding to the various molds of different diameters it is desired to employ in the machine. 7 Means are provided .for readily inserting and removin as .by provi with rings 175, into which suitable lifting hooks of suitable power or hand lifting vices may be connected, for readily raising and lowering said molds, and for causing proper meshing relation between the ars of said molds and the racks on the mac ine, in order to produce proper desired corelated movement between said molds and the heating'slab. v After the printing plate hasbeen curved, (see Fig. 13), it may be submitted to sub sequent operations of shavin theinner face of the printing plate, solidifying, and cor-' recting' the same, and trimming the edges thereof, in any desired manner.

- In operation, the mold carriage is adjusted to its proper retracted position, accordin to the diameter of mold which it is desire to em loy, as by placing the adjustable stop pin 1 2 in its proper hole 173, and retracting the carriage so that its stop 171 coacts with the stop 172.

The desired rollable mold isthen inserted molds of different diameters, mg the bearings 122 thereof too in the carriage, and the teeth of its ears brought-into -mesh with the teeth-0 the rack. v The hook-bar 141 is then'placed over i the lip 143 of the mold, and the flexible band 51 brought under proper tension by adjustments of the adjusting screws 155.

The flexible band under tension and the printing plate are wrapped about the rollable mold, for instance, as shown in dotted lines in Fig. 8. As the rotation of the rollable j mold progresses along the rack, the teeth of its gears coact with the teeth of the rack for maintaining the flexible band in stretched relation, and maintaining the rollable mold parallel with relation to the printing plate, which has been placed parallel with relation to it, for insuring proper curvature of the printing plate.

When the printing plate has been thus formed, the carriage is retracted by operation of the hand wheel 136, whereupon the curved printing plate is removed from the machine.
